Satire these days is always too late. 
And yes, washing hands with soap is the biggest and most effective weapon against this virus we know of so far. (If one gets tired of singing “Happy Birthday”, by the way, and is a “Star Trek” fan one can also recite “Space… the final frontier. These are the voyages of the starship Enterprise. Its ongoing mission to explore strange new worlds . To seek out new life and new civilizations. To boldly go where no man has gone before!”)
